\multicolumn{4}{p{\textwidth}}{\textit{Note:} The table reports the group-average marginal effects (G-AME) of \textit{change of government} on \textit{bureaucratic turnover} obtained from predictions using OLS models with fixed effects for tenure, decade and ministry. The models also includes covariates for election year and government independence, as well as a set of individual characteristics: age, gender, and temporary appointment. The WWII years are dropped from all models. Standard errors are clustered on individuals. The dependent variable is turnover of individual bureaucrats. The N-row displays the number of individual-year observations, followed by the number of employment spells and the number of bureaucratic turnover events. The variation in N is due to panel 2 only including level-1 bureaucrats.} \\
